Figure 1: The figure is a graphical representation of the price of PVC pipe as a function of pipe diameter.
Figure 2: The figure is a graphical representation of the price of PVC pipe as a function of pipe diameter and in this case the small diameters are highlighted.
The excel spreadsheet with the primary data is available here
Discussion
